Title: Recording element drive control system
Inventor: NAMEKAWA TAKESHI
IPC: B41J2/36
Filed: 1984-01-09
Abstract: PURPOSE:To permit a nearly perfect elimination of irregularity of a recording density caused by variation of voltage of a power source for recording by detecting voltages applied to a recording element at two or more different checking times and by controlling the driving time of the recording element in accordance with the detected values. CONSTITUTION:When a non-stabilized power source such as a battery is used as a recording power source 22, the output voltage Vth rather slowly changes, [waveform (a)] at the time of no load applied, however, if an exothermic body is driven, it changes [waveform (b)]. The volume of power source voltage decrease and its waveform inclination at the time of driving are mainly depending on a magnitude of the load of electric current, namely, the number of exothermic bodies 21 that are simultaneously driven. Supporting that during the driving period of exothermic bodies power source voltage Vth changes at a certain slope, from the power source voltage V1 after a time t1 elapsed from the start of driving t0, and from the power source voltage V2 after a time t2 elapsed, the driving time required for a fixed volume of heat generation of exothermic bodies 21 is calculated by ROM26. The signal ENB is turned on for the above driving time by a timer 27 and by fixing the volume of heat generation from exothermic bodies, the unification of recording density is devised.

IPC: H01L21/318
Filed: 1997-01-09
Abstract: PROBLEM TO BE SOLVED: To improve resistance to dielectric breakdown while large capacitance is maintained by using a silicon nitride film of high permitivity, by constituting a capacitor dielectric film in the parts which are in contact with an upper and a lower electrodes, of silicon nitride films of high density as compared with the part which is not in contact with the electrodes.

High density silicon nitride films 3A and 3C which are in contact with the lower electrode 2 and the upper electrode 5 have high density as compared with a low stress silicon nitride film 3B which is not in contact with the electrodes. The dielectric film which is in contact with the electrodes 2, 3 and has possibility of dielectric breakdown due to pin holes does not reach dielectric breakdown, because the high density silicon nitride film is used. Except the silicon nitride film which is in contact with the electrodes 2, 3, the silicon nitride film of low stress is used, so that deterioration of reliability due to film stress becomes hard to be generated.

The molding die 20 is made up of a cylindrical member 21 and a collar member 22 in such a way that the center part 20'a is of thin section and both end parts 20b are of thick section. In addition, heat is transmitted to the center part of the inner rubber roll blank ahead of the rest so that the foaming process takes place in the center part earlier than the end part sides and is sifted to the end part sides in succession.  The center part of the rubber roll blank is brought into contact under pressure with the inner peripheral face of the molding die following the expansion of the blank. Next, the blank is made to come into contact under pressure with the end part sides of the die to collect an internal gas at the end part sides and push the gas out of a gas vent hole 23a. The cavity face 24 of the molding die 20 is formed so that the degree of cylindricality is 0.1 mm or less and the level of deformation under torsion when the rubber molding are rotated is 0.2 mm or less.

IPC: A61B6/03
Filed: 1989-01-09
Abstract: PURPOSE:To achieve a higher quality of a picture by switching a resetting period and an integration period alternately with the control of a plurality of switches to prevent effect of noises. CONSTITUTION:A photodiode (Pd) 5 generates an electric charge corresponding to a dose of X rays transmitted through an object to be inspected and a switch changeover control section 14 turns ON switches SW1, SW2 and SW4 during a resetting period. At this point, the electric charge of the Pd 5 stored in a capacitor C1 is discharged to lower an output e0 of an operational amplifier 13 and an offset voltage Vos thereof 13 is applied to a capacitor C2. Then, with the entry of an integration period, the control section 14 turns ON the switch S3 and a detection current of the Pd 5 is charged into the capacitor C1 so that the electric charge of the capacitor C1 increases according to a quantity of incident light and the output e0 of the operational amplifier 13 increases too response to the increase in quantity. At this point, a voltage of the capacitor C2 cancels the offset voltage VOS to turn a terminal voltage of the Pd 5 down almost to zero. Thus, integration and resetting are performed alternately to offset a resetting voltage, thereby enabling the prevention of effect of noises.
